    pci hdtv tuner questions

    i was thinking that since hdtv reception is a lot cleaner than the regular analog reception, maybe in a car situation it would work better if i could put in one of those pci hdtv tuner cards sold by ati or avermedia.

    If it is possible what would i need (im a noob when it comes to hdtv)

    will i need to get one of those hdtv tuner boxes to tune the stations or will the card do that on its own? a regular antennnae to recieve the signal? or anything else..

    If youre only using the analog antenna as input, what is the point of displaying it in hi def? It won't take the fuzz out!

    The card will tune stations, but they dont come with an antenna, they just have coaxial input to plug the tv cable in. In a car, the only thing you could plug in is an antenna.

    Just a regular tv tuner card, hi def is unnecessary with ANALOG signals, which is what comes over the air. While it may improve analog and non hi def digital signal clarity, the only thing that will make the tv signal stronger with an antenna is a signal booster.

    Apparently so.... but they havent rolled it out completely yet.

    Receiving DTV signals over the air requires an antenna and a new DTV receiver that can decode the digital signals. In general, an antenna that provides quality reception of over-the-air analog TV signals will work for DTV reception.

    Not entirely correct. There are numerous stations in the larger markets that are broadcasting DIGITAL signals over-the-air (called OTA DTV for over-the-air digital-TV). From what I've read, a regular VHF/UHF antenna would work, since many stations broadcast their digital signal in the UHF range (generally above channel 13). So, you can get digital TV signals using a vhf/uhf antenna.

    You can view the list of "DTV Stations on the Air" via the FCC website at http://www.fcc.gov/mb/video/files/dtvonair.html

    Yeah, your'e right, I remembered hearing about DTV and did a and found the link below. I didn't want to mislead, thanks for the correction. According to the link I provided, it may not play right on all tv's, but a regular antenna will pick up the signal.

    From the link:

    How Do I Get DTV?

    Receiving DTV signals over the air requires an antenna and a new DTV receiver that can decode the digital signals. In general, an antenna that provides quality reception of over-the-air analog TV signals will work for DTV reception.

    so what exactly are we saying here im a little confused with all the terminalogy?

    with the hdtv tuner card + regular antenna = hdtv channels in analog quality
    or
    with the hdtv tuner card + regular antenna = hdtv channels in digital quality
    or
    with hdtv tuner card + dtv tuner box (or whatever its called)+ regular antenna = hdtv channels in digital quality

    btw i live int he chicagoland area so ota hdtv channels are available in my area.

    I would think the hdtv card would decode the signal without the decoder box mentioned, since it is a digital tuner card. (duh!)
    In general, an antenna that provides quality reception of over-the-air analog TV signals will work for DTV reception.
    I guess the picture quality will be limited to the signal strength, and reception ability of the antenna, but digital nonetheless.
